Will 20 gallon sender work in 16 gallon tank.
I am going to have to buy new tanks after I shorten the frame on my K10. Can I keep the old sending unit from the 20g tank? I will need to see what shape they are in but if they are good then it would be nice to use them instead of buyng new.

Yes.
THe tanks depths are identical. The 16g is just shorter than the 20g tank

Re: Will 20 gallon sender work in 16 gallon tank.
That was my perception but I wanted to make sure. Thanks.

Re: Will 20 gallon sender work in 16 gallon tank.
While on the subject, would a 20 gallon sender work in a 31 gallon suburban tank??

Re: Will 20 gallon sender work in 16 gallon tank.
The fill neck vent line for a 'burban tank is part of the sending unit, waaay different from truck style. Plus, rest of the tubes are facing different directions.

Re: Will 20 gallon sender work in 16 gallon tank.
I see, thank you. Is there a difference in sending units for the pre 86 sending units and the 87-91? I know the tanks are different. I'm going to be using a baffled tank for my 5.3 swap.

Tank openings are all the same, so you *could* technically put an 87+ sending unit/pump into an older tank, but it wouldn't have the baffles. Baffled would be my choice though.

Re: Will 20 gallon sender work in 16 gallon tank.
No problemo. I have an LQ4 on a stand for my truck, one of these days (years), so I've looked into what I need as well.

Re: Will 20 gallon sender work in 16 gallon tank.
I installed 16 gallon tanks when I converted my CC to a short bed and did nothing else. Everthing works just fine.
On a seperate, but maybe related note, I would like to do a Suburban tank and move my gas door to the Suburban location on my CC. Any reason this wouldn't work? I have a parts Suburban with all the parts. Tired of having to move the truck if I want to fill both tanks!
